In this study, we computed the scattering amplitude for classical black-hole scattering to third order in the Post-Minkowskian expansion, confirming a conjectured relation between the real and imaginary parts of the amplitude and agreeing with a recent computation by Damour based on radiation reaction in general relativity.
We compute the scattering amplitude for classical black-hole scattering to third order in the Post-Minkowskian expansion, keeping all terms needed to derive the scattering angle to that order from the eikonal formalism. Our results confirm a conjectured relation between the real and imaginary parts of the amplitude by Di Vecchia, Heissenberg, Russo, and Veneziano, and are in agreement with a recent computation by Damour based on radiation reaction in general relativity.
